Why is my concentration so poor?

Poor concentration can be frustrating. You may find your mind wandering during work, struggle to focus while reading, or have difficulty completing tasks that require sustained mental effort. Many factors can contribute to poor concentration, from lack of sleep and exercise to stress and underlying health conditions. The good news is there are strategies you can use to sharpen your focus and train your brain to concentrate better.

Common Causes of Poor Concentration

Several factors commonly impact one’s ability to concentrate:

Lack of sleep

Not getting enough quality sleep prevents your brain from functioning at full capacity. Adults should aim for 7-9 hours of sleep per night. Lack of sleep makes it harder to focus, pay attention, and retain information.

Stress and anxiety

When you feel highly stressed or anxious, these emotions can preoccupy your mind. Worrying about stressful situations and events takes up mental bandwidth that could otherwise be devoted to the task at hand. Chronic stress also impairs concentration over time.


When you try to juggle several tasks at once, your attention becomes divided. Focusing on multiple streams of information makes it hard to fully concentrate on any one task.

Information overload

Today’s nonstop influx of information vie emails, social media, and 24/7 news can overwhelm your brain. Information overload hampers your ability to focus and process information deeply.

Poor diet

What you eat affects your brain function. Refined carbohydrates, sugar, and junk food lead to energy crashes that disrupt concentration. A diet high in nutrients like omega-3s, antioxidants, B vitamins, zinc, and magnesium supports focus.

Lack of exercise

Regular exercise benefits brainpower. Aerobic activity boosts blood flow and oxygen delivery to the brain. When you’re sedentary, you’re more prone to distractions and mental fatigue.

Technology overuse

Frequent digital distractions from phones, email, social media, and the internet fracture attention spans. The constant stimulation impairs your brain’s ability to focus.

Medical Causes

In some cases, an underlying physical or mental health condition contributes to poor concentration, including:


Attention deficit hyperactivity disorder (ADHD) involves difficulty sustaining attention. ADHD also comes with symptoms like impulsivity and restlessness. Adults with undiagnosed ADHD often struggle with focus.

Depression and anxiety

Symptoms like chronic worry, racing thoughts, and rumination make concentration difficult for those with depression, anxiety disorders, OCD, and PTSD.

Sleep disorders

Conditions like insomnia, sleep apnea, and restless leg syndrome disrupt quality sleep necessary for optimal focus. Treating the disorder can improve daytime concentration.

Medication side effects

Some medications for conditions like high blood pressure, allergies, and diabetes can cause side effects like brain fog and drowsiness, impacting concentration.

Nutrient deficiencies

Being deficient in nutrients affects cognitive skills. Deficiencies in iron, vitamin B12, and vitamin D are linked with impaired thinking and focus.

Substance abuse

Abusing drugs and alcohol alter brain chemistry and neurological pathways in ways that significantly reduce concentration and impair cognitive abilities.

Head injuries

Traumatic brain injuries, even mild concussions, can damage parts of the brain involved in focus, attention, concentration, and memory.

Tips to Improve Concentration

If you don’t have a medical condition contributing to your concentration difficulties, there are practical strategies you can implement to sharpen your focus:

Minimize distractions

Create an environment conducive to concentration by reducing external distractions. Silence phone notifications, close extra browser windows, and find a quiet space to work. Noise cancelling headphones can also help block out distracting sounds.


Focus on one task at a time. Multitasking splits your concentration, decreasing productivity and increasing mistakes. Devote your full attention to the most important task until complete.

Take breaks

Taking regular short breaks maintains focus better than sitting for prolonged periods. Take a quick 2-5 minute break every 30-60 minutes to stretch, walk around, or get a drink of water.

Use productivity tools

Apps like Focus@Will, Forest, and Freedom limit internet access so you can concentrate without online distractions. Web blockers like StayFocusd block distracting sites.

Reduce stress

Chronic stress impairs concentration. Build in daily stress management techniques like deep breathing, meditation, walks outdoors, or journaling to calm your mind.

Get organized

Clutter and disorganization sap mental focus. Keep workspaces, files, and tasks organized so you can concentrate without unnecessary search and decision fatigue.

Improve sleep habits

Aim for 7-9 hours nightly, limit screen time before bed, avoid caffeine late in the day, and develop a calming pre-bed routine to get quality, restorative sleep crucial for concentration.

Exercise regularly

Aim for 30-60 minutes of aerobic activity at least 3-5 days per week. Exercise increases blood flow to the brain and stimulates neurotransmitters that sharpen focus.

Eat brain-boosting foods

A diet rich in fruits, vegetables, healthy fats, proteins, and key nutrients nourishes the brain. Stay hydrated and limit processed foods and refined sugars.

Change your scenery

A new workspace helps stimulate focus, especially if you’re fatigued with your current workspace. Step outside, head to the library, or work from a cafe.

Make lists

Break big tasks down into bite-sized steps and write them down. Checking off completed subtasks provides a satisfying sense of progress.

Set goals

Define specific, measurable goals for what you want to accomplish during each concentration session. Goals provide incentive to minimize distractions.

Reward yourself

Build in small rewards for staying focused, like enjoying a favorite tea or taking a walk mid-project. Positive reinforcement strengthens concentration stamina.

When to Seek Help

If you’ve made lifestyle and environmental changes but still struggle to concentrate, consult your doctor. They can check for underlying causes and recommend specialists like sleep doctors, psychiatrists, neurologists, or nutritionists to further assess your difficulties.

Diagnosis and treatment of conditions like ADHD, anxiety, depression, sleep apnea, and nutrient deficiencies can improve concentration challenges and quality of life. Prescription medication may be warranted in some cases based on the diagnosed condition.

Cognitive behavioral therapy (CBT) also helps treat ADHD and strengthen mental focus. Your doctor may suggest neuropsychological testing to evaluate your specific cognitive weaknesses and strengths.


Difficulty concentrating is frustrating, but various strategies can bolster your ability to focus. Reduce distractions in your environment, take breaks, minimize stress, get organized, improve sleep habits, exercise, eat a brain-healthy diet, and set specific goals.

Chronic concentration challenges may require medical assessment to diagnose and manage underlying conditions. With the right lifestyle changes and treatment if needed, you can regain your ability to concentrate for improved work performance, learning, and well-being.
